A fluoride selective electrode is a type of ion selective electrode sensitive to the concentration of the fluoride ion. A common example is the lanthanum fluoride electrode. In the lanthanum fluoride electrode, the sensing element is a crystal of lanthanum fluoride (LaF 3), doped with europium (II) fluoride (EuF 2) to create lattice vacancies.

2022年10月3日 · In this study, an all-solid-state fluoride ISE was prepared using a LaF 3 single crystal with a poly(3,4-ethylenedioxythiophene (PEDOT) solid contact to an Ag electrode. PEDOT can be deposited on a substrate by the planar process; moreover, its high redox capacitance can lead to a stable fluoride SC-ISE.

A new modified ion-selective electrode with membranes of LaF3 single crystals with different internal contacts (solid steel or electrolyte) and with FexOy nanoparticles as loading was developed. The best response characteristic with linear potential ...

2019年1月15日 · We fabricated fluoride-sensitive EIS sensor using thermally deposited poly LaF 3 membrane. The effect of deposition temperature on the structural and sensing properties of poly LaF 3 was investigated. Poly LaF 3 sensor formed at 500 °C exhibits high sensitivity, low limit of detection, small hysteresis voltage and small drift rate.

1994年11月21日 · In this study, the non-stoichiometric dissolution behavior of LaF3 powder and single crystals in contact with aqueous solutions has been identified and characterized with respect to its relation to ion-selective charge separation at the solid I solution interface.
